Cell Discovery
T/F The cell membrane allows some things to enter/leave the cell, and blocks other things from doing so.
True. This is called selective permeability.
This jelly like substance fills the space inside a cell. It is semi-fluid and is composed of water and dissolved materials.
What is cytoplasm?
This powerhouse organelle provides the cell with the ATP it needs to break down sugars.
What is the mitochondria?
These are a group of cells working together.
Tissues
T/F. Cells can be seen with the naked eye
F. You need a microscope to observe plant and animal cells.
This organelle directs cell processes by providing DNA instructions. It is centrally located and is called the "command center" for the cell.
What is the nucleus?
These are minute particles found in large numbers in the cytoplasm and sometimes on ER.
Ribosomes
These are organs working together
The objectives are located at the top of the body tube
False. This is the eyetube
This organelle is a series of flattened membranes. Cell products pass through these membranes and become packaged for delivery in or out of the cell.
What is the Golgi Body
This organelle digests worn out cell parts and also plays a role to defend the cell from infection.
What is a lysosome?
What are structures that carry out the functions of a cell called?
Organelles
The eyepiece holds a 100x magnification
F. It holds a 10X magnification
This organelle is the "transportation system" for the cell. Proteins and lipids are synthesized (put together) here also. There are two varieties 'S' and 'R'.
What is the Endoplasmic Reticulum, or ER?
These are found in the nucleus and carry genetic information.
chromosomes
By the arm and by the base. Hold slides on edge with fingers. Don't ever touch the place where the speciman lies.
list each statement of the cell theory... list the 3 statements
1. All living things are made of cells. 2. Non-living things are not made of cells 3. every living organism begins with a cell.
Is an organism a complete living thing? Give 2 examples and contrast and compare.
T. Plants and animals. Answers may vary.
This organelle is a storage container for water and waste. It's central in plant cells and spread out and diverse in animal cells.
What are vacuoles?
The three differences between plant and animal cells are:
1. Plant cells have cell walls. 2. Plant cells have chloroplasts 3. Plant cells have a central vacuole.
Using a body system, explain cells, tissues, and organs working together.
Answers may vary--up to teacher's discretion!
